Salina, NY--The U.S. Navy has awarded Lockheed Martin a contract with a value that could go as high as $940 million to make devices that jam roadside bombs.

The initial order for the Symphony Radio Controlled Improvised Explosive Device Defeat jammer systems is for $40.8 million. The contract runs through September 2014.

The system is mounted on vehicles.

"The system was engineered and built to provide continuous electronic force protection against RC-IEDs in the most rugged, tactical and extreme environments," said Carl Bannar, vice president and manager of Lockheed Martin's Radar Systems business based in Salina.

The device is compatible with other communication and jamming systems.

Lockheed Martin began making the devices in 2006, and has delivered more than 1,000 systems. It has received orders of $126 million prior to this latest order.

Much of the work on the systems will be done at Lockheed plants in Florida and Virginia.
